Question

describe the conditions necessary for digestion of starch by amylase

Answer 1

starch is broken down into glucose units which is further broken down into CO2 and water through the process of glycolysis.

as food enters the mouth food are broken into small pieces and salivary gland produces saliva. salivary amylase then hydrolyze starch into maltose. but complete digestion occurs in pancreas by pancreatic amylase,

temperature - all enzymes are proteinaceous in nature thus at very low temperature enzyme is deactivated and at higher temperatures enzymes gets denatured. thus it will take more time to digest starch at very high and low temperatures. optimum temperature is 32 -37 degree in which lesser time is required to digest starch and enzyme will be more active.

optimum pH of the enzyme ranges between 6-7 . fluctuations in the pH leads to denaturation of enzymes. enzyme salivary amylase is most active at pH 6.8. salviary amylase does not function in stomach since stomach has high level of acidity due to which enzyme get denatured and alter its shape.
